It's understandable if fantasy baseball owners are getting excited for Yoon's arrival considering the recent success of other pitching imports from Aroldis Chapman (Cuba) to Yu Darvish (Japan) to Hyun-jin Ryu (Korea), not to mention the hoopla this offseason around the Yankees signing Mahahiro Tanaka (Japan). But fantasy owners should temper their expectations for Yoon.

He doesn't have Chapman's blazing fastball. Yoon, 27, sits around 91-92 mph, occasionally hitting 93. At 6-feet tall, Yoon isn't as physically imposing on the mound as Darvish. By all accounts, he's not as polished as Ryu, who enjoyed a strong first MLB season with the Dodgers last year. Some scouts say Yoon has an above-average changeup, but he lacks a signature pitch like Tanaka's splitter.

That's not to say Yoon can't have success in MLB. He was the KBO's MVP in 2011 after logging a 2.45 ERA and 178 strikeouts in 172.1 innings for the Kia Tigers. He is coming off a disappointing season, though, fighting through a shoulder injury to post a 4.00 ERA and 76-28 K-to-BB ratio in 87.2 between starting and relieving.

Assuming Yoon is healthy (and passes Baltimore's notoriously strict physical), he should compete for Baltimore's fifth rotation spot this spring. Fantasy owners would likely rather see prospect Kevin Gausman in that role, though. As a rookie starter in the AL East, Yoon would likely be relegated to AL-only leagues or spot-start duty for mixed-leaguers.

Yoon does have relief experience, too, and has even closed in Korea. Baltimore's ninth-inning job is unsettled, so the potential for saves might be Yoon's best shot at becoming a fantasy sleeper for 2014.
